I find autoiso very useful for all sorts of shooting, including weddings where I know the lighting will be changing from good to bad often. I just choose the creative options of shutter speed and apperture, put on manual, activate autoiso, and presto....Nikon magic

re: put on Manual...

That's what I hate most about Auto ISO on my Nikon. It's great in A/S modes, but when I flick to Manual mode, I want full manual. Nine out of ten times I switch to M, it's because the camera's meter is not exposing the subject how I want or i want consistent exposures. Having the ISO change automatically based on what the camera thinks is right when in Manual mode is very frustrating to say the least!

2: Nevertheless, Nikon do it lots better. Canon don't take it seriously and have never really tried to make it useful. Last time I looked at the Nikon version, it was almost good enough to be something you'd want to use. It may have improved further since then. The Canon version is just one of those pages in the manual you glance at once when the camera is new, shrug, and turn the page, thinking "what's the point of that feature? I'll never use it".

using autoiso isnt really manual though is it, you are still letting the camera decide something.....what's the difference using apperture or shutter priority and fixing the other two variables ?

if you want full manual, go full manual

agree, what I want though is to be able to use AutoISO in any semi automatic mode (ie. A/S/P) but when i 'turn the dial' to M mode, I want the camera to turn AutoISO off. I don't have time at a wedding to drive through the menus to turn AutoISO on/off everytime I need to flick to Manual mode.

You can put in on the quick menu (which is what I have done)....you could even program it to a function button I suppose

But I also use autoiso in A and S mode also, so, wouldnt want it to turn off and therefore change automatically. I hate when machines do that, if I want it on, i'll turn it on, if i want it off, i'll turn it off

What you are doing is essentially elevating ISO to be the equal of aperture and shutter speed - in other words, making a new mode to stand alongside Av (camera decides shutter speed, you decide everything else), and Tv (camera decides aperture, you decide everything else) - call it "Iv" (camera decides ISO, you decide everything else).

I tried the quick menu, but takes my eye away from viewfinder. I'm pretty sure i found you can't program it to a function button as that would be a decent compromise for me

I can see why it's of benefit in M mode for some shooters - set A&S to get desired effect and let AutoISO do the rest but it turns "M" into another semi automatic mode where the shooter has little control over the final exposure. Maybe there should be another mode on cameras for autoiso: P / A / S / I / M - that would solve it!
